“Nancy Bilyeau’s passion for history infuses her books.”
–bestselling historian and novelist Alison Weir

Coming in April:
Genevieve Planché returns in The Versailles Formula, the third book in the historical suspense series.
Genevieve has left the dangers of London for a quiet life in the countryside with her husband and young son. But when she is invited to a dinner party at Sir Horace Walpole’s magnificent Gothic estate, she is drawn into a terrifying web of deception, espionage, and murder.
Days after the mysterious dinner party, Genevieve makes a shocking discovery — a secret pigment of the deepest, purest blue is being produced once more. The formula is so rare, it’s the obsession of chemists, royalty, and spies.
Some will kill to possess it. Others will kill to keep it buried.

About Nancy
Born in Chicago and a graduate of the University of Michigan, Nancy moved to New York City to work in the magazine business as a writer and editor. After working for publications ranging from Rolling Stone to Good Housekeeping, she turned to fiction. She wrote the Joanna Stafford trilogy, a trio of thrillers set in Henry VIII’s England, for Touchstone/Simon & Schuster. For her Genevieve Planché novels—The Blue, The Fugitive Colours, and The Versailles Formula—she drew on her heritage to create a Huguenot heroine. Nancy is a direct descendant of Pierre Billiou, a French Huguenot who immigrated to what was then New Amsterdam (later New York City) in 1661. Nancy’s ancestor, Isaac, was born on the boat crossing the Atlantic. Pierre’s stone house is the third oldest house in New York State.
